Police in the northern province of Quang Ninh have recommended charges against 19 members of a gang that allegedly trafficked more than 370 kilograms of drugs from Laos to Vietnam and China.

They are hunting for six more members of the ring led by Nguyen Thi Bich Ngoc, 42.

By the time it was busted in April the gang was said to have smuggled 346 kilograms of heroin, 25 kilograms of methamphetamine, and 200,000 tablets of synthetic drugs since 2007.

The police said gang members brought the drugs from Laos over the border into the central Vietnamese provinces of Thanh Hoa and Quang Tri, and then transported them to Hanoi, Ho Chi Minh City, and northern provinces for sale.
